AbstractPromoter methylation is an important mechanism of regulating E-cadherin expression. Methylation-specific PCR (MSP) assay was done to evaluate the promoter methylation status of E-cadherin gene in primary tumor samples from 23 cases of Chinese women with invasive ductal breast cancers. Western blotting assay was employed for E-cadherin and β-actin expressions. Positive MSP results occurred in 26.1% (6/23) of primary tumor samples and none of four normal skin samples. These molecular events tended to occur in breast cancers associated with poor prognosis. Whereas the mean ratio of CDH1/β-actin for six MSP-positive cases was 0.0290 ± 0.0355, the mean ratio for 17 MSP-negative cases was 0.4726 ± 0.5049 (P = 0.046). In conclusion, aberrant E-cadherin methylation preferentially occurs in invasive ductal breast cancer associated with poor prognosis and is one of the mechanisms of E-cadherin expression silence in breast cancers from Chinese women.
